In consequence, fly ash is a heterogeneous material. SiO 2, Al 2 O 3, Fe 2 O 3 and occasionally CaO are the main chemical components present in fly ashes. The mineralogy of fly ashes is very diverse. The main phases encountered are a glass phase, together with quartz, mullite and the iron oxides hematite, magnetite and/or maghemite.
This study investigates the feasibility of cofiring fly ashes from different boilers, circulating fluidized beds (CFB) or stokers as a sustainable material in alkali activators for ground granulated blastfurnace slag (GGBS). The mixture ratio of GGBS and cofiring fly ashes is 1:1 by weight. The results indicate that only CF fly ash of CFB boilers can effectively stimulate the potential ...
A set of data from the British Geological Society of 11 coal ash samples showed that even the lowest level of scandium seen in these samples was worth nearly US5000 per tonne of fly ash, with the more enriched ashes reaching over US40,000 per tonne of fly ash, and the maximum germanium levels at almost US3500.
